3-2-3 Virtual Server

This function allows you to redirect a port on Internet IP address (on WAN port) to a

specified port of an IP address on local network, so you can setup an Internet service

on the computer on local network, without exposing it on Internet directly. You can

also build many sets of port redirection, to provide many different Internet services

on different local computers via a single Internet IP address.
